amoeba_dup on rich_text field raises NoMethodError: undefined method 'macro' on nil:NilClass

[goulvench]

Version 3.2 of Amoeba doesn't support cloning rich_text attributes using the include_association syntax.

The error raised is the same as in issue #79:

# Running…
object_with_rich_text.amoeba_dup
# Raises…
NoMethodError: undefined method `macro` for nil:NilClass
from '/usr/local/bundle/gems/amoeba-3.2.0/lib/amoeba/cloner.rb:110' in `follow_association`

The customize syntax allows working around that limitation though, here is what works for me:

class MyClass
  has_rich_text :content

  amoeba do
    customize ->(original, cloned_object) do
      cloned_object.content = original.content
    end
  end
end

Under-the-hood, rich text associations are defined using has_one :"rich_text_#{name}", it would be nice if Amoeba was able to clone action_text natively, let me know if a PR would be welcome.

@goulvench Thank you for raising this. If you want to have a go at a PR that would be very much appreciated. Although I've become a maintainer I am a long way from being an expert (yet) but I am hoping to get this gem more actively maintained.

I have added the label 'enhancement'. Do you think this is appropriate, or would you consider it a bug? It should at least fail silently, which would suggest it is a bug.

Hi, I would qualify this as a bug since rich_text are has_one associations and they are supposed to work out of the box. Plus ActionText has been around for quite a while now.

I'll see if I can work something out but I also have tons of work at the moment so I may not find time before a while. I'll let you know.

Apart from that, Amoeba works like a charm and I was able to implement a requirement in just the time it takes to read the docs, so thanks for this gem!

Thanks for pointing this out @goulvench, it seems that this issue is also occurring when working with active_storage.

I had to do this as a work-around

class MyClass
  has_one_attached :picture

  amoeba do
    customize(lambda { |original, new_object|
      new_object.picture.attach(original.picture.blob)
    })
  end
end

will look into the codebase and see if this can be rectified

Also, when copying a (source) record that has a rich text field, the new (copy) record has an ActionText::RichText, but it does not persist the ActionText::RichText association.
